Abstract: A dental orthosis is provided for use in the treatment of snoring. The upper portion of the device receives the upper teeth of a user. Once properly fitted, the device will firmly grip all upper teeth forward of the premolars and remain positioned independent of natural motions of the lower jaw. The lower portion of the device is formed into a ramp structure whereby natural jaw motions result in the engagement of the lower teeth against the ramp, which will cam the lower jaw into a more forward position. An aperture in the device between the upper portion and the lower portion facilitates the passage of air for mouth breathing and attracts the tongue forward. By inducing the lower jaw and tongue to a more forward position, the device induces a more open posterior airway in the user, resulting in a significant reduction in snoring.
